Time-weighted rates of return can be calculated on a daily basis using a method known as Daily Valuation, or by using a slightly less accurate but in some cases more convenient monthly method known as Modified Dietz where inflows and outflows are averaged for the month.

method to arrive at the solution. 4 You’ll also see that my first guess (which typically is the solution from Modified Dietz) failed to provide a solution to the equation. And why is this? Because the IRR appears not to support returns at or below -100%, which seems to be a deficiency, because there are obviously cases when one can lose more than 100

This is because provincial securities regulators will require advisors to report money-weighted rates of return, which are less useful for benchmarking. By using an approximate time-weighted rate of return (such as the Modified Dietz method), investors will be better able to gauge their performance relative to index benchmarks. The modified Dietz ratio is similar to the dollar-weighted return, but it has the advantage that we do not require a solver to find the exact rate of return. The modified internal rate of return is recommended by the Investment Performance Council (IPC) under their Global Investment Performance Standards ( GIPS ). Time-Weighted Return: There is actually more than one TWR calculation and they include: the Original Dietz method, the Modified Dietz method and the Daily Valuation method. The best method of these three is the Daily Valuation method, which gives you a “true” TWR. TWR breaks the total performance for a desired period into sub-periods that are defined by any occurrence of an external cash flow. As the name of the return indicates, the return is weighted on the amount of time in each period. Time Weighted Rate of Return (TWRR) Finally, another way to calculate the return of the portfolio is the Modified Dietz method. This is often referred to as the Modified IRR (MIRR), as it is The Dollar Weighted Rate of Return would be 18.6%, and the Time Weighted Rate of Return would still be 20%. Finally, because financial service providers typically provide only Time Weighted Rate of Return, and because the actual calculation methods for Time Weighted Rate of Return (Daily Valuation and Modified Dietz) yield similar results, there is no reason to believe that one company does it better than another.

Comparison with time-weighted return and internal rate of return[ 

Time-Weighted rate of return (TWR): There are several ways of computing TWR, but the “Modified Dietz method” is the most common. In a TWR calculation, you compute returns for smaller discreet time frames (like one month at a time) and then geometrically link the returns of those time periods together to calculate the return for the entire time horizon . Time-weighted rates of return can be calculated on a daily basis using a method known as Daily Valuation, or by using a slightly less accurate but in some cases more convenient monthly method known as Modified Dietz where inflows and outflows are averaged for the month. method to arrive at the solution. 4 You’ll also see that my first guess (which typically is the solution from Modified Dietz) failed to provide a solution to the equation.
